Froblins AI simulation, tesselation, & rendering, all entirely on the GPU - SIGGRAPH 2009

I’ve seen the Froblins demo before with 3000 creatures scurrying around the screen. But always thought this was primarily a hardware tesselation and rendering demos.  Turns out it is also about concurrently running interactive Artificial Intelligence code on entirely on the GPU.  The full story is parallel artificial intelligence computation for dynamic pathfinding and local avoidance on the GPU, massive crowd rendering with LOD management with high-end rendering capabilities such as GPU tessellation for high-quality close-ups and stable performance, terrain system, cascaded shadows for large-range environments, and an advanced global illumination system.
